Does heat turn a white LED into a dim blue LED?

[duffy]

The phosphor's missing? Oh, wait - I know. Firefly larva need to eat phosphor so they can light up at night, see, so...

I haven't seen fireflies for about 47 years.

My new white LED is still glowing brightly after 3 hours. Its top is sticking out of the case and feels quite warm but not hot. The top of the case is so hot that I can touch it for only a couple of seconds.

My new white LED has been running perfectly for over 10 hours so the problem is fixed.
